RELATED APPLICATION

The present invention is a continuation application of U.S. Patent Publication No. 2018/0132205 published May 10, 2018, which claims benefit of U.S. Provisional Patent Application Ser. No. 62/417,540 filed Nov. 4, 2016, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present embodiments are directed to the field of antennas, and more particularly, to antenna monitoring systems and related methods.

BACKGROUND

It may be desirable to have antennas aligned, not only for operation, but for increased communication efficiency. In particular, directional antennas, for increased communications efficiency, are typically aligned in multiple directions to obtain a desired coverage or communications pattern.

Present day alignment techniques may be relatively time consuming and involve using a technician on a tower and test equipment to physically adjust a given directional antenna to achieve the desired alignment. For example, a given directional antenna may be physically adjusted in any of azimuth, roll, and tilt, in an attempt to align or adjust a given directional antenna.

Over time, a given directional antenna may become out of alignment, for example, by weather, equipment aging, etc. thereby causing communications inefficiencies. Thus, it may be desirable for a given directional antenna to be periodically realigned, for example, using the techniques described above. However, this process may take a relatively large amount of time given the number of directional antennas in operation.

U.S. Pat. No. 8,766,872 to Dalmazzo is directed to an autonomous wireless antenna sensor system. More particularly, Dalmazzo discloses three subsystems: a wireless antenna sensor, a remote sensor control station, and a remote graphic user interface (GUI). Measured antenna information is transmitted from the wireless antenna sensor to the remote sensor control station at ground level. The remote sensor control station retransmits the measured antenna information to the GUI.

DETAILED DESCRIPTION

The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout, and prime notation is used to indicate similar elements in alternative embodiments.

Referring initially to FIGS. 1-2, an antenna monitoring system 20 for directional antennas 21 a-21 n includes a cloud based server 30. The directional antennas 21 a-21 n may be geographically spaced apart and carried by respective towers 23 a-23 n, for example, and may be microwave antennas and/or cellular antennas. Of course, the directional antennas 21 a-21 n may be other and/or different types of antennas and may define other and/or additional types of communication links (e.g. powered, unpowered, etc.).

The antenna monitoring system 20 also includes sensor devices 50 a-50 n. While several sensor devices 50 a-50 n are illustrated in FIG. 1, it should be understood that the system 20 may include far more sensor devices, for example. Each sensor device 50 a includes a portable housing 51 a to be mounted on a respective directional antenna 21 a, for example, to a rear or back of the respective directional antenna, and an alignment sensor 54 a carried by the portable housing 51 a. The alignment sensor 54 a is configured to sense alignment of the respective directional antenna 21 a.

The alignment sensor 54 a may include a tilt sensor, a roll sensor, and an azimuth sensor, for example, for measuring tilt, roll, and azimuth, and these parameters may be used to sense the alignment of the respective directional antenna 21 a as will be appreciated by those skilled in the art. The alignment sensor 54 a may alternatively or additionally include an accelerometer, a microelectromechanical (MEMS) accelerometer, an optical azimuth sensor, a magnetometer, and/or a gyroscope for sensing respective parameters. With respect to an optical azimuth sensor, it will be appreciated by those skilled in the art that the optical azimuth sensor may operate in either or both of the visible and non-visible ranges. For example, an optical azimuth sensor that operates in both the visible and ultraviolet (UV) ranges (e.g., for sensing optical emissions) may be desirable for improved sensing under increased cloud coverage. Of course, each sensor device 50 a may include more than one alignment sensor 54 a, and/or the alignment sensor may include other types of sensors, for example, geographic position, height, etc., as will be appreciated by those skilled in the art. Each sensor device 50 a also includes a cellular telephone transceiver 55 a carried by the portable housing 51 a.

Referring now additionally to FIG. 3, the cloud based server 30 includes a processor 31 and a memory 32 coupled thereto. The processor 31 is configured to provide a user interface 33 associated with the alignment data for the sensor devices 50 a-50 n. The user interface 33, for example, may be a physical user interface or graphical user interface (GUI) and/or may include a communications interface for remote communication and user interfacing therewith. In other words, in an embodiment, the user interface 33 may be a communications link, port, or other interface to permit data from the cloud based server 30 to be displayed, for example, on a mobile phone, tablet, computer, or other device associated with the user. The user interface 33 may communicate data and or errors using any one or more mediums and protocols, for example, web requests, TCP/IP or UDP, EDI, SMS, and email. Alternatively or additionally, the user interface 33 may provide raw measurement data. Of course, the user interface 33 may communicate using other and/or additional protocols and techniques.

Each sensor device 50 a also includes a controller 52 a carried by the portable housing 51 a. The controller 52 a is configured to collect alignment data from the alignment sensor 54 a, and communicate with the cloud based server 30 via the cellular telephone transceiver 55 a. In some embodiments, the controller 52 a may communicate or send the alignment data to the cloud based server 30 via the cellular telephone transceiver 55 a. The controller 52 a may send the alignment data periodically. Alternatively, the controller 52 a may send the alignment data continuously.

The controller 52 a may alternatively or additionally process the alignment data and send a misalignment notification based thereon. For example, when the processed alignment data is indicative of a misalignment, the misalignment notification may be sent to the cloud based server 30 for display via the user interface 33. In some embodiments, the misalignment notification may be sent to the user without passing through the cloud based server 30. The misalignment notification may be in the form of an email, text message, or other type of protocol notification, and may be communicated to other and/or additional devices associated with a user, as will be appreciated by those skilled in the art.

Each sensor device 50 a may also include a battery 56 a carried by the portable housing 51 a. The battery 56 a may power the alignment sensor 54 a, the cellular telephone transceiver 55 a, and the controller 52 a. Referring briefly to FIG. 4, in some embodiments, each sensor device 50 a′ may be powered by a supercapacitor circuit 59 a′ carried by the portable housing 51 a′. The supercapacitor circuit 59 a′ is charged by ambient RF power to thereby power the alignment sensor 54 a′, the cellular telephone transceiver 55 a′, and the controller 52 a′.

The cloud based server 30, upon receipt of the alignment data, may store the alignment data and permit retrieval thereof via the user interface 33. The cloud based server 30 may also forward the alignment data via the user interface 33. For example, the processor 31 of the cloud based server 30 may generate and send an email including the alignment data. Of course, the cloud based server 30 may forward the alignment data in other and/or different formats.

Similar to the controller 52 a of each sensor device 50 a, the cloud based server 30 may process the alignment data and send a misalignment notification based thereon via the user interface 33. In other words, the cloud based server 30 may also send a misalignment notification either in addition to or instead of each sensor device 50 a-50 n. The misalignment notification may be in the form of an email, text message, or other type or protocol notification, and may be communicated to other and/or additional devices associated with a user, as will be appreciated by those skilled in the art and described above.

For example, the cloud based server 30 may transmit collected results (e.g. raw measurement data), via the user interface 33, to network operation centers or other maintenance facilities for further analysis, evaluate data for errors or values beyond pre-programmed tolerances, transmit data based on detected errors to network operations or other maintenance facilities, and receive acknowledgements of receipt of transmitted data or errors to network operation centers or maintenance facilities. The cloud based server 30 may also receive and process commands and/or raw measurement data directly (e.g., eliminating the need to access cloud based GUI) from network operations centers or other maintenance facilities. The cloud based server 30 advantageously provides a cloud based GUI for users to access for reviewing collected data, setting up data retrieval methods and frequency (e.g. a number of web requests for the latest data every X minutes), administering thresholds for determining out of bounds conditions to be reported (e.g., relatively large changes in tilt produces a notification to network operations center), commissioning, registering and decommissioning sensors in the network, grouping of sensors into logical groups for reporting and review, administering access to users and their roles, and associating business data with individual sensors (e.g., address, identification number). Of course, the cloud based server 30 may provide or perform other and/or additional functions.

The cloud based server 30 also may include or provide an administrator interface 34 for the sensor devices 50 a-50 n. Similarly to the user interface 33, the administrator interface 34 may communicate using any one or more mediums and protocols, for example, web requests, TCP/IP or UDP, EDI, SMS, and email. Of course, the administrator interface 34 may communicate using other and/or additional protocols and techniques. The administrator interface 34 may permit the review of collected alignment data, setting of data retrieval methods and frequency, administration of thresholds for determining out of bounds conditions to be reported (e.g., misalignments), commissioning, registering and decommissioning sensor devices, grouping of sensors into logical groups for reporting and review, administering access to users and their roles, and associating business data with individual sensors (e.g., address, identification number), for example. The administrator interface 34 may permit other and/or additional administrator functions, as will be appreciated by those skilled in the art.

As will be appreciated by those skilled in the art, the antenna monitoring system 20 may be particularly advantageous in that it eliminates the need for a further relay device. In particular, since the sensor devices 50 a-50 n communicate via the cellular transceiver 55 a, the monitoring system 20 eliminates the need for a nearby site controller with its associated spares, power, and other maintenance issues, for example. By using the cellular transceiver 55 a, for example, the monitoring system 20 may also be less geographically limited than systems that rely on WiFi, for example.

Referring now to FIGS. 5-6, in another embodiment, each sensor device 50 a″ may include another sensor 61 a″ carried by the portable housing 51 a″. The other sensor 61 a″ may be a height sensor, a geolocation sensor, a temperature sensor, a humidity sensor, a light sensor, or a camera, for example. There may be more than one other sensor 61 a″, which may be of different types.

The controller 52 a″ collects other data from the other sensor 61 a″. The controller 52 a″ may communicate the other data to the cloud based server 30″. The cloud based server 30″ may provide the other data for the other sensor 61 a″ via the user interface 33″.

A method aspect is directed to a method for monitoring directional antennas 21 a-21 n. The method includes operating sensor devices 50 a-50 n, each sensor including the components and functionality described above. The method also includes operating the cloud based server 30 to provide the user interface 33 associated with the alignment data for the sensor devices.
